Advanced web page content management

ABSTRACT

Controlling contents of interfaces may include receiving multiple interfaces presented on a display screen. The multiple interfaces may include at least one primary task interface and each of the multiple interfaces may present at least one content item. A user engagement level with respect to content items presented via the multiple interfaces may be estimated. A degree of user effectiveness with respect to progression toward completing a primary task presented via the primary task interface may be determined. A content item may be selected from the multiple interfaces based on the user engagement level and the degree of user effectiveness. A presentation of the selected content item may be made in a controlled manner on an unused portion of at least one of the multiple interfaces.

FIELD

The present application relates generally to computers and computer applications, and more particularly to interface, browsers and web page management.

BACKGROUND

A display screen may display multiple windows of content, e.g., web pages, tabs or interfaces open in one browser, in multiple browser instances, or in multiple browsers. The multiple windows of content may be opened for purposes such as communicating on social media, listening to music, browsing, performing online tasks and activities (e.g., editing online and/or web content, interacting with backend, cloud service, or another system processing), monitoring (e.g., monitoring for news events, sporting events, reports for web traffic, weather, and/or another item), entertainments and/or other purposes.

Some of the opened tabs, web pages, or interfaces may be more important or time sensitive than others, for instance, due to the user activity or task, nature and characteristics of the content or information being displayed on the web page or interface. However, for example, for some users, the cumulative effect of the time spent in switching tabs or web pages may not be affordable, for example, as a user may need to switch from one tab to another tab to find the tab that the user is interested in. Switching from one content to another (e.g., presented via a tab, a web page or interface) may affect a user's engagement level with respect to the user's primary task or activities. For example, a user can lose attention with respect to the user's current task and the user's sentiments, cognitive states and emotional states (e.g., mood, tiredness) may change in relation to the ongoing activities. Such events may cumulatively affect the degree of user effectiveness toward completing the user primary task.

DETAILED DESCRIPTION

A system, method and techniques may be provided that intelligently manage interface or web page arrangements on a display (e.g., browser window or windows) presenting content items, for example, so as to improve a task completion rate of an activity being performed on an interface, web page or the like. In some aspects, a user's effectiveness may be predicted with respect to tasks or activities other than the user's primary tasks or activities, for example, for improving the user's overall task completion rate, for instance, with an acceptable quality threshold. A content item may be dynamically selected or aggregated from a web page and arranged such that the content item would not affect the overall task productivity of the user. An unused part or portion of at least one interface or web page may be determined to present a content item determined to be relevant to the user's activities. In some aspects, at least one interface or web page may be split to present the content item determined to be relevant to the user's activities. In some aspects, content items displayed or presented on one or more interfaces or web pages, which may contribute to ineffective outcomes (e.g., user's predicted effectiveness) may be learned and dynamically de-prioritized or suggested to be removed (or removed) from an interface or web page.

A method and/or system in some embodiments may intelligently manage and control content items of web pages and/or interfaces, for instance, to improve a user's overall task completion, for instance, with an acceptable quality threshold. Intelligently managing and controlling the content items may be based on predicting user effectiveness and analyzing a content relevance. For example, multiple web pages or the like (e.g., interfaces that include content displayed or presented online) displayed or presented on a display screen may be identified. At least one of the multiple web pages (or interfaces) is associated with a user's primary task being performed, for example, in real-time. Each interface or web page displays or presents at least one content item. A user's engagement level may be estimated or determined with respect to the displayed or presented content items and the one or more primary tasks of the user (e.g., with the content item presented on a web page or interface associated with the user's primary tasks). The user's context and cognitive state may be analyzed and the degree of user effectiveness may be determined in relation to progression towards completion of the one or more primary tasks. One or more content items determined to be relevant may be selected from one or more web pages (interfaces) based on analyzing content item relevance and the degree of user effectiveness. In some aspects, a method and/or system may present or display, and/or control the selected one or more content items determined to be relevant, on unused part or parts of at least one web page (or interface), for example, which may improve the user's overall task completion rate.

As more and more tabs, web pages or interfaces open with explicit content items that are part of online user activities or tasks, user effectiveness with respect to the user's primary activity or activities (task or tasks), for example, the completion of a primary activity and the quality associated with the primary activity may increase or decrease. A method and/or system according to some embodiments intelligently manage a web page or interface to improve a user task completion, for example, by displaying or presenting selected relevant content items for a user, for example, on unused part or parts of at least one web page, based on predicted user effectiveness. In some embodiments, the user effectiveness may be predicted as a function of attributes such as user progression score, context analysis, task or activity characteristics, content item characteristics, for example, in an area where a task is being performed that requires improving the user's effectiveness (e.g., completion of a task). In some aspects, intelligently controlling the content item displays may improve overall task completion rate with an acceptable quality threshold. In some aspects, acceptable quality attributes of the task may be given or may be determined based on analyzing task specification details, e.g., obtained from a collaborative project management application such as an issue tracking system. The acceptable quality thresholds or attributes may be specified on a task metadata or may be extracted from previously ranked quality thresholds or attributes on similar tasks.

FIGS. 1A-1D illustrate web page or interface content management in one embodiment. FIG. 1A shows a web page or interface which presents an electronic mail (e-mail) application, and a primary task of composing an email. A mail application shown in FIG. 1A, for instance, may include an area that shows content related to an inbox 102, an area with messages 104 and another area that allows a user to utilize a chat function 106. A pop-up screen or panel 108 may be populated or shown for composing a new message. FIG. 1B shows two unused zones that are identified in the web page (or interface) showing the mail application, for example, identified as a primary task interface or web page. The vacant space in Unused Zone 1 110 arises from having only a few e-mail in the inbox, and Zone 2 112 is determined to be unused by analyzing the historical behavior of the user to conclude that the user does not use the chat application using the area at 106. FIG. 1C illustrates analyzing multiples web pages or tabs (or interfaces) to assess user engagement with the content items in order to determine relevant content, and subsequently to predict the user effectiveness. In this example, one or more browsers or the like may also have other web pages or interfaces opened, for example, one associated with a live traffic flow 114 and another associated with a streaming event 116. Responsive to determining that the relevant content enhances the user effectiveness, the content or information of the content 118, 120 may be displayed in the unused zones as illustrated in FIG. 1D. In some aspects, the information may be derived content (e.g., updated current scores 120 of the teams playing in the sporting event rather than the streaming video of 116), which is derived from the content determined to be relevant.

In one aspect, a computer process or thread implementing the method may run, for example, in the background, while the user interacts with the content items on or across one or more web pages, and continuously analyze each opened web page or interface where the user has visited at least one time. The computer process may further profile each web page based on the analysis results and other external metadata. The web page (interface) profile and other external metadata may provide a basis for determining content item relevance or importance (and hence the corresponding web page or interface that is presenting or displaying the content item) and assigning a content item relevance score in relation to at least one primary task of the user. In some aspects, the current user context and cognitive state may be also determined that may affect a degree of user effectiveness level in completing a user's primary task.

The system may dynamically rank a web page based on the web page profile and content analytics that may provide further details for determining the relevance score of the content item with respect to the user tasks or user effectiveness towards completing one or more primary tasks. The ranking and relevance scores of the web page (and content item) may change as the user continues interacting (and thus engaging) with one or more content items, task profile, and detected content item characteristics. In some embodiments, IBM® Watson Content Analytics from International Business Machines Corporation (IBM)®, Armonk, N.Y., may be used to collect and analyze content items and/or web pages.

In some embodiments, a method and/or system may estimate the user engagement, for example, which may be measured at least in part by the frequencies of visiting a web page, the time spent per each visit (e.g., reading), user's interactions with a content item, analysis of eye movement, gaze patterns, the profile of the webpage, and/or other factors. The method of estimating the user engagement may be done using custom trained machine learning models or algorithms. By way of example, the Markov chain algorithm described below may be employed to analyze the user reading patterns.

In one implementation of an embodiment, in the below algorithm, V_(i) is a random variable representing the portion of the content item viewed at the i-th time, v_(i) is the observed areas of interest viewed at the i-th time, and n is the number of times user transitioned from one portion of the content item to another (or from one page to another if the transition is between web pages). The probabilities P(V_(i)=v_(i)) and P(V_(i)=v_(i)|V_(i-1)=v_(j)) can be directly estimated from user activity stream data, e.g., by counting the number of transitions from v_(j) to v_(i) and ensuring proper normalization (v∈O P (V=v|V_(j))=1). “O” represents possible state outcomes, which may include {Click, Pause, Scroll Up, Scroll Down, Zoom-in, Zoom-out, Type, Read, or another}. Index i−1 represents a view time (e.g., i−1^(th) time) before the view at i-th time. Similarly, j represents the view at j-th time, where i, j∈{1, 2, . . . , n} and where j>i.

${P\left( V_{1\text{:}n} \right)} = {\sum\limits_{k = 1}^{K}{\alpha_{k}{P_{k}\left( {V_{1} = \upsilon_{1}} \right)}{\prod\limits_{i = 2}^{n}\;{P_{k}\left( {V_{i} = {{\upsilon_{i}❘V_{i - 1}} = \upsilon_{i - 1}}} \right)}}}}$

The above representation in one embodiment may model to estimate the average user engagement. For instance, the modeling to estimate the user engagement can be done using a variant of Markov chains (e.g., discrete mixture of Markov chain), which can take into consideration different user engagement patterns, which may be present in the user data. In the above algorithm, P_(k)(V₁) and P_(k)(V_(i)|V_(i-1)) represent the probability distributions, α_(k) is a mixture weight and k indexes the mixture component.

The system may also estimate the current progression of the user towards a completion of a task or a set of tasks based on the user progress so far. In some embodiments, a method of estimating the current progression is based on analyzing data streams that may include the number of code commits (or lines of code written), the number of transactions submitted, analysis of documents generated or submitted (e.g., number of words written in a word document, portable document format (pdf) document submitted, and/or others). The method of estimating the current progress may further be based on similarity analysis from cohort of users and cohort of tasks. For example, a total number of tasks, a number of users assigned to the tasks and completed tasks may be utilized to determine the user's progress in comparison to others and respective completion rates for reference points.

User effectiveness represents the degree of the effectiveness of a user in terms of the ability of the user to complete or engage in one or more user primary tasks. A method and/or system in some embodiments may estimate or predict the user ability to complete a specified task in a predefined time with acceptable quality attribute or attributes (which may be predefined) based on the estimated progression, estimated degree of the user engagement, analyzing historical data (of similar task cohort) and given acceptable quality attributes of the task, and analyzing task specification details (e.g., obtained from a collaborative project management application, which for example, may provide services such as version control, source code management functionality and other services). An acceptable quality threshold or attribute (or thresholds or attributes) may be specified on a task metadata or may be extracted from previously ranked quality thresholds or attributes on similar tasks. In some aspects, task metadata may be obtained by analyzing data from monitoring activities, for example, for information such as a user's progression rate, tasks assigned, work done in stipulated time period, time spent on respective web pages and web content viewed.

Determining the user effectiveness, for example, estimating or predicting the user's ability to complete a specified task in a predefined time may further take into consideration the analysis of the user motivation, working style, and prior knowledge or expertise level of the user in the given task or tasks (or similar task or tasks). Such information may be made available in a user profile. A user profile may be constructed or built in some embodiments.

Based on the estimated progression of a user u (u∈U) on one or more tasks T (Prog_(u∈U)(T)) and measured quality attributes, a method and/or system in some embodiments may determine the degree of user effectiveness in relation to progression toward completion of the one or more user primary tasks (Eff_(u∈U)(T)). Prog_(u∈U)(T) represents the progression of user u for corresponding task T. For example, user effectiveness, Eff_(u∈U)(T), may take on a value of “Very High (5)”, “High (4)”, “Medium (3)”, “Low (2)”, or “Poor (1).” User effectiveness may be represented in another form or value. If the estimated degree of user effectiveness is below a threshold Δ ((Eff_(u∈U)(T)<Δ), a method and/or system in some embodiments may automatically or autonomously trigger a content selection that may further dynamically select one or more content items from a content web page (interface) store using one or more relevant content selection factors. The one or more relevant content selection factors may include content relevance score, user profile (e.g., user context, cognitive state, and/or other user factors), engagement level, and task profile.

For example, in FIG. 1, an example of a primary task is illustrated as composing an email, and the effectiveness of the user (user effectiveness) may be quantified by the number of words typed per minute. If a method and system in some embodiments detects that the users is constantly changing tabs to check the progress of a streaming event, or monitor traffic (e.g., because the user needs to travel to a location), then the method and/or system may determine that displaying the some data associated with the streaming event (e.g., sporting event score) or traffic information may enhance the user efficiency by not needing to switch between tabs. On the other hand, if the method and/or system detects that a form (e.g., a visualization) of a presentation or display (e.g., a graph or map) is distracting the user which is reducing the quality of the primary task (e.g., increase in the number of spelling mistakes), then the method and/or system may reduce the form (e.g., graph or map) to a simple informational data, e.g., traffic data such as “delay at road x”. If the method and/or system still detects that the quality of the email is poor (e.g., the user is still making many spelling mistakes), the method and/or system may automatically or autonomously add a dictionary lookup in an unused space, e.g., which may help to enhance the productivity of the user.

FIGS. 2A-2C illustrate transforming web page or interface content in one embodiment. For example, reducing the content to another form (e.g., a graphical traffic map to simple text data, a stock activity graph to a simple share price), may help the user from being distracted from the user's primary task. For instance, a graphical display at 202 in FIG. 2A may be transformed to another form, for example, shown at 204. FIG. 2C shows an example of adding a dictionary lookup window 206 or like, which may improve the process of editing (e.g., improve spelling), which may increase the quality of the task of composing an email as an example.

In some embodiments, the content items may take the form of widgets, which are live and interactive. A widget, for example, may be an application, or component of an interface, that enables a user to perform a function or access a service, and may be provided as a graphical user interface (GUI) element with which a user may interact. For example, both the traffic widget and sports event widget may update in real-time. If the user clicks on the widget, the user may be taken to the web page from where the content originates.

In some embodiments, a method and/or system, which may intelligently manage selected one or more relevant content items, may also detect one or more unused parts of at least one web page (or interface). In some embodiments, a method and/or system may split or section at least one web page or interface to display the selected one or more relevant content item. The characteristic and location of content items may be determined in runtime based on analysis of an unused part of the web page or GUI.

FIGS. 3A-3D show examples of detecting an unused part or portion of an interface or web page in one embodiment. FIG. 3A shows an interface or web page of an e-mail application, and for example, a primary task of composing an e-mail message. An unused part detection function, for instance, identifies two zones 302, 304, which may be used to display relevant content from another interface or web page. In this example, a blank space (or the like in a user interface display representation) may be identified as an unused portion. FIG. 3B shows an interface or web page of software or code development application, and a primary task of writing software code on the interface or web page of the code development application. In this example, consider that the code development application's interface uses a portion of the display window (e.g., right side column shown at 306) for providing an application feature, for example, a notification menu, or another feature. An unused part detection function may identify that the user does not usually use (or is not interested in) this particular application feature when employing this application to write code. Such determination, for example, may be performed by looking at or analyzing historical data of the user's usage of the application. In this example scenario, an unused part detection function may identify the notification menu portion as unused portion 306.

Referring to FIG. 3C, consider that an interface or a web page is of an application that presents or streams a video, allowing a user to watch a video via the interface. A primary task is identified as watching a video. Consider also that the interface of this application includes a comments section (e.g., for allowing a user to enter comments) and/or recommendation section (e.g., which may recommend other videos for the user to watch), for example, displayed simultaneously with the primary task section (showing the current video being watched). In this example, the unused part detection function may determine that the user may not be interested in the recommendation shown in the portion shown at 308 (labeled Zone 1), or the comments in the portion shown at 310 (labeled Zone 2). For instance, the unused part detection function may monitor user activities on the interface and determine that the user has not used those features of this application. The method and/or system in some embodiments may use those portions 308, 310 to display other relevant content.

Referring to FIG. 3D, consider that an interface or a web page is of a social network application, which may feed news on a user's social network page. In this example, the unused part detection function may determine that the user may not be interested in some of the notifications appearing on a portion of the user's social network page, for example, shown at 312 (labeled Zone 1), and/or a portion showing links to other pages, shown at 314 (labeled Zone 2). For instance, a method and/or system in some embodiments may determine an unused part, by implementing facial recognition detecting and mood analysis of image and/or other data received via a device such as a webcam camera, e.g., in correlation with the web content being monitored. As another example, a method and/or system in some embodiments may implement user gaze detection to map a line of sight with a portion of content currently being viewed and/or monitored, along with user clicks or the like (via an input device) and an amount of time spent related to a particular content Like features may allow the method and/or system to understand a level of interest of a user pertaining to a specific localized content on the page.

Thus, the system and/or method in some embodiments may automatically detect unused parts of an interface or a web page and use those portions to provide or arrange content on a GUI that may increase user's effectiveness in processing a primary task.

In some embodiment, a user may choose to manually allocate a zone on a primary web page or interface where relevant content from other web pages can be displayed. FIG. 4 shows an example of an interface or web page, on which a user may manually allocate a zone in one embodiment. In some embodiments, the method and/or system may automatically determine the relevant content. In some embodiments, the relevant content may be selected by a user. For example, a webpage may be divided into content segments or sections. An interactive graphical user interface (GUI) which can displace the contents locally or in hypertext markup language (HTML) form can be used to dynamically position the content or can be specified by the user with a respective position on a display screen, for example, using a virtual intermediate layer.

FIG. 5 is a diagram illustrating a method of intelligently managing a web page or interface in one embodiment. The method may be performed by at least one hardware processor. At 502, an opening of a web page (or interface) or a tab in a browser, may be detected or received. For instance, a user may open a new tab or web page or interface, for instance, to browse or navigate. A browser or the like displaying or presenting the new tab or web page or interface receives a location identifier such as a uniform resource location (URL) from where the new tab or web page or interface may be retrieved and presented, for example, on a user interface display.

At 504, a primary (also referred to as a priority) tab or web page or interface among the web pages, tabs, and/or interfaces which are opened is identified. In some aspects, a primary page may be identified as the user's most viewed and/or operated page, where the content can be specified and allocated at different unused zones on a display screen. Initially, in some aspects, a primary page can be set manually by a user or can be identified dynamically based on time spent by the user and the functions performed on the page.

At 506, all opened web pages or tabs or interfaces or the like, are evaluated or re-evaluated. For example, in some embodiments, a feedback learning mechanism may be provided as part of a machine learning aspect, which understands activities such as the frequency of gazing, operating at particular web content, tasks being assigned to the user, and/or other activities, which may lead to changing interests or level of engagement of the user.

At 508, for 1 to n opened web pages or tabs or interfaces (e.g., for each of the opened web pages or tabs or interfaces, for example, determined at 506), relevant content from the web page (or tab or interface) is determined. In some embodiments, relevant content of a web page, tab or interface may be determined based on a web page ranking or relevant scoring determined based on external metadata. Webpage ranking may be performed based on features such as operating on a particular web page content, time spent on a page, a frequency of use of a page. For instance, a web page having higher number of activities, time spent and frequency may be ranked higher. A web page ranking may determine the priority of web pages. A relevant scoring may rank portions or content segments within a particular web page, for example, based on a user's focus (e.g., pattern of eye gaze, input activity (e.g., clicking, mouse hover, and/or others), and/or others) associated with a portion or segment.

In some embodiments, relevant content of a web page, tab or interface may be determined as follows. User effectiveness may be estimated. The content of the opened web pages (or tabs or interfaces) may be analyzed, for example, by performing a text classification or another analysis. Such analysis may determine topics of interest to the user, for example, based on history of the topics the user has previously visited or viewed may be determined. A user context estimation may be performed, which determines web pages (or tabs or interfaces or the lie), in which the user spends most time, for example, based on historical user behavior with respect to web pages (or tabs or interfaces), and determines similar web pages (or tabs or interfaces) that are in the currently opened set. A web page (or tab or interface) may be determined to be similar to another web page (or tab or interface), for instance, if the content of the web page (or tab or interface) meets a similarity threshold to the content of another web page (or tab or interface). A user cognitive state analysis may be performed that determines user attention and/or interest, for example, by detecting the user's eye movement, gaze, input device activity such as a mouse activity, and/or facial micro expressions. In some embodiments, a machine learning mechanism with input features (e.g., the user's eye movement, gaze, input device activity such as a mouse activity (e.g., clicks, hover-over), frequency, time, tasks assigned, level of engagement, and/or facial micro expressions) may train a machine learning model to determine a relevant scoring of specific content. Examples of a machine learning algorithm, which may train a machine learning model may include, but are not limited to, linear regression, logistic regression, neural networks such as deep learning neural networks, and/or others. Supervised machine learning, for example, trains a model based on a labeled training data set, and to be able to predict an outcome given an input feature vector or input feature values.

At 510, most relevant and/or effective information or content may be culled or selected from a group of relevant content determined at 508. In some embodiments, more than one content item may be selected as being most relevant. For instance, content ranked highest, or a number of content ranked highest may be selected.

At 512, the primary web page or tab or interface may be rendered, for example, with the most relevant and/or effective information determined at 510 from another web page or tab or interface. For instance, the content from another web page may be overlayed over a portion or portions of the primary web page, for example, over an unused part of the primary web page.

At 514, user activity may be monitored and re-evaluated. For instance, user consumption of the content overlayed over a portion of the primary web page may be monitored, and/or user opening a new web page (or tab or interface) may be detected. Based on the monitored activities, the method and/or system in some embodiments may re-evaluate the determination of the most relevant content and may dynamically update the presentation of the content on the unused part or parts of the primary web page (tab or interface). For example, the processing at 510 and 512 may iterate or repeat based on new activities of the user.

In some embodiments, the method and/or system may reconfigure itself based on a single user or multiple users. For instance, if multiple users are logging in to that same computer or even on different computers, then, based on their respective credentials such as biometric information (finger detection), voice detection, facial detection to login to the computer, the method and/or system may adjust the relevant content to display or overlay on a primary interface or web page or tab based on the specific user. For instance, every individual user may have the respective user's own preferences or set of relevant contents and the users may be detected to identify or re-configure the settings.

The method and/or system may create a separate cognitive state or identity for each user in order to configure the prioritized content by extracting relevant effective information from multiple web pages. Hence, the content determined to be of interest to a specific user (e.g., based on their interests, cognitive heuristics) may be dynamically displayed or presented responsive to retrieving or receiving that content, for example, from a database (e.g., which may be stored remotely (e.g., in a cloud database) or locally). In this way, an intelligent decision of displaying or presenting a customized content for a specific user can be made. The content presented or displayed may be more personalized and may pertain to a particular user's cognitive interests and history.

In some embodiments, the portion or portions of the web page that presents or displays unused content may be utilized to highlight the user's activities, completed task and a rendering of the user's task to complete, for instance, in the form of a visualization chart or charts. Such visualization, displayed on the unused portions or sections, for example, created dynamically on the web page, may enable dynamic evaluation of the user's progress with respect to tasks completed and activities being performed by the user. As an implementation example, backend Javascript may enable the creation of dynamic web pages and visualization charts, which highlight the user's effectiveness and time spent on the respective web pages along with tasks under progress. FIG. 6, as an example, illustrates visualization charts and highlighted dynamic code created, for instance, on unused sections of a web page, in one embodiment. The visualization highlights user's activities along with time spent on different tasks and various web sources and/or items. The highlighted code shows an example of a code, e.g., dynamic Javascript code, which may be created, for example, in a backend layer to show an illustrative graphical representation of user's progress, tasks and time spent on different web page content for self-analysis, shown in the unused portion to provide or present (e.g., to a user) user a broad perspective of the user's progress.

As described above, a method and/or system in some embodiments may include estimating the degree of user effectiveness. In some embodiments, the estimating of the degree of user effectiveness may be configured to continuously learn the user effectiveness with respect to the displayed (or presented) content item or items on one or more unused parts of the web page in association with the predicted effective or ineffective outcomes. The learning may use gaze patterns analysis, and identify the areas of the web page or interface, on which the user most frequently focuses. The learning may include cautioning against, de-prioritizing or suggesting to remove content item or items, or a web page to be displayed, that are associated with predicted ineffective outcomes for the user. For instance, responsive to determining that displaying a video content is known to be associated with a poor outcome with respect to the user's primary task being performed on a primary interface or web page, that content item may be suggested to be removed, or moved to a less relevant category. Thus, for example, if a detected impact of the content item or items is decreasing the rate of the user progression or completion ability, a method and/or system in some embodiments may dynamically de-prioritize or suggest that the displayed content item or items be removed or not displayed. For instance, referring to FIG. 1, displaying a traffic map may be determined to distract the user from performing the user's primary task on an opened interface (primary interface or web page), for example, of composing an e-mail message. In response, the method and/or system may reduce the graphical live traffic map to a simple text data. If the method and/or system still determine a reduction in effectiveness of the user, despite the change in the display form, then the method and/or system may remove that information (text data) altogether.

In some embodiments, a cloud memory storage system may store the activities and cognitive states of the respective users. The method and/or system may determine personalized display choices based on the specific user logging onto a computer at a particular point of time.

While the above examples described a web page content management, the method and/or system may also be implemented to manage content in native applications deployed and/or running on a computing device such as a mobile phone, tablet, personal computer, laptop and/or another device. In a similar manner, the method and/or system may detect unused parts of the user interface (e.g., GUI) of a particular app or application, and insert relevant content from other apps or applications running on the computing device, into this unused space of the particular app or application.

In some aspects, a computing device may be an edge computing device, for instance, where the selective personalized content can be cached for multiple users for quick retrieval and displayed (dynamic GUI) in a prioritized fashion according to the engagement level of those respective users on their respective web sites, interfaces, and/or tabs of interest.

FIG. 7 is a flow diagram illustrating a method of intelligently managing and controlling contents of interfaces (e.g., web pages) in one embodiment. The method may improve a user overall task completion, for instance, with an acceptable quality threshold, which may be predefined. The method may include predicting user effectiveness and analyzing content relevance. The method may be performed or executed by at least one hardware processor.

At 702, multiple interfaces (e.g., one or more web pages, tabs, pages of apps (applications), and/or or another interface) presented, for example, on a display screen may be received. The multiple interfaces may include at least one primary task interface and each of the multiple interfaces may present at least one content item.

At 704, a user engagement level may be estimated with respect to content items presented via the multiple interfaces. For instance, the user's activity or interaction with each of the multiple interfaces, for example, including interaction with the primary task interface, may be analyzed to determine the user engagement level with respect to content items presented on the primary task interface and other interfaces of the multiple interfaces. In some aspects, a user engagement level may be computed per user, and may include multiple values, e.g., computed for each content. For example, a user engagement level may include multiple values based on the priority of the content and the positioning of the respective content for a user. As another example, a user engagement level may include multiple values based on the priority of the content and the positioning of the respective content for each user of a group of users.

In some embodiments, estimating or determining a user engagement level may include analyzing the user interaction patterns, for example, with the multiple interfaces, estimating the user context (e.g., the current activity of the user, current state of the user) and determining the user cohort (e.g., progression state, understanding level, cognitive state) with respect to content items on the multiple interfaces. User context refers to information or attributes associated with a user. User cohort refers to a group of users (e.g., viewing a screen together). A method and/or system in some embodiments may detect preferences of respective users (e.g., by automated detection mechanisms such as a facial recognition technique) and may dynamically alter the content based on an averaging mechanism.

In some embodiments, a user engagement level may be estimated at least based on a user's frequency of navigating to an interface of the multiple interfaces, time spent per visit to the multiple interfaces, a degree of user interactions with the multiple interfaces, and user eye movements and gaze patterns. For instance, user engagement level may be computed with respect to a specific web page content, for example, which may be calculated using a likelihood probability.

At 706, a degree of user effectiveness may be determined with respect to progression toward completing a primary task presented via the primary task interface. In some aspects, the degree of user effectiveness with respect to progression toward completing a primary task presented via the primary task interface may be determined at least based on user motivation, working style, and user's expertise level associated with the primary task. For instance, user activities may be tracked via monitoring sources such as sensor feeds and one or more applications (e.g., for receiving calendar, schedule, agenda items), to compute user's progression rate. In some aspects, machine learning may take as input at least some of the tracked information to computer a user's progression rate. Information or data may be extracted, e.g., from social media or the like to determine working style and expertise. In some aspects, the degree of user effectiveness may be determined based on an estimated progression rate of the user on one or more tasks and the measured quality attributes.

At 708, a content item from the multiple interfaces may be selected based on the user engagement level and the degree of user effectiveness. In some aspects, a degree of user effectiveness may be used as an input to content selection, which may decide or optimize which content items are best suited for the user, for instance, from multiple candidate content items. In some aspects, a content item or content items may be selected without a measure of the user effectiveness. In one aspect, content relevance of each of the multiple interfaces may be determined, for example, from a user engagement level, for example, determined by analyzing the user's activity or interest with the content items associated with, or presented on, the multiple interfaces. In some aspects, the content item may be selected further based on content profile, task profile, characteristics of content items, user context and a user cognitive state. So for example, a content item may be selected based on one or more content selection factors such as a content relevance score, user profile (which may include user context, user cognitive state, and/or other information associated with the user), engagement level, and task profile. In some aspects, content relevance score may be determined based on an estimated engagement level and content profile, characteristics of content items, user context and cognitive states. In selecting one or more content items, some of the above specified variables can be turned on or off (used or not used), for example, depending on a constraint considered in the selection process. For example, a constraint may include increasing the user effectiveness.

At 710, a presentation of the selected content item on an unused portion of at least one of the multiple interfaces may be controlled. For instance, the selected content item may be displayed on the unused portion of the primary task interface. In some aspects, controlling the presentation of the selected content item may include transforming a display of the selected content item from one form to another. For instance, graphical displays may be transformed to simpler text form. In some aspects, controlling a presentation of the selected content item on an unused portion of at least one of the multiple interfaces may increase a rate at which the primary task is completed. Such arrangement of content item display may improve the user overall task completion rate.

In some aspect, a visualization chart may be constructed dynamically based on a user's progression of the primary task performed via the primary task interface. For example, a dynamic visualization chart may be constructed or rendered dynamically based on the progress of the user with respect to the task handled or taken up by the user within a predefined time period T.

In some aspects, the method may also include detecting one or more unused portions in the primary task interface, for instance, for displaying one or more content items determined to be relevant. For instance, one or more content items may be from a popular page or interface, where the user frequently visited.

In some aspects, the method may also include continuously learning the degree of user effectiveness with respect to presented content item on the unused portion. Learning may include monitoring user gaze patterns and identifying the user's focus on areas of the primary task interface. Based on the learning, the content item presented on the unused portion may be de-prioritized or removed. In another aspect, based on the learning, the content item may be suggested or recommended to be de-prioritized or removed.

In some aspects, a multi-layer machine learning classification model (e.g., deep learning) may be provided or implemented, which is able to predict the most relevant content and identify the unused sections of an interface such as a web page from a number of opened interfaces (e.g., web pages). The content may be dynamically managed, for example, to ameliorate the user's task completion rate and improve the efficiency of completing a task performed on an interface (e.g., webpage). For instance, a method and/or system may identify one or more primary tasks, present (e.g., display or cause to display) and control content item or items (e.g., determined to be relevant) on unused parts of at least one interface (e.g., webpage). Such controlling of the content item presentation may improve the user's overall task completion rate.

In some aspects, unused zones in individual interfaces (e.g., web pages) can be utilized by adding content from a separate interface (e.g., web page), for example, so that all information that the user wants to frequently access is consolidated in one area. A method and/or system, for example, which may implement a cognitive learning aspect and an understanding of contextual activity of the user, may allow for an improved task completion rate while meeting predefined quality thresholds and attributes. A method and/or system in some embodiments may also dynamically generate and add (or insert) to an unused portion of an interface, content such as one or more graphs or another visualization (and/or another information form), for example, which may show users progress and list of activities currently being performed or have been performed. Such dynamic content may show a realistic progress over time to indicate user's efficiency on one or more tasks performed via one or more interfaces.

In another aspect, the processor may be programmed with one or more of the various functionalities described herein.

A user task database or store (e.g., storage device) 802 may store information such as metadata associated with tasks. Metadata information may include quality attributes and thresholds associated with a task, for example, a quality level the task when completed needs to meet.

A task profiler 804 may create a task profile (e.g., per task) based on the information stored in the user task store 802. For example, a task profile associated with task T specifies a quality attribute associated with that task T.

A user model database or store (e.g., storage device) 806 may store information associated with users. Such information may include user context, cognitive states of the users, knowledge levels of users, and/or other information.

A content analyzer 812 may perform analysis (e.g., text analysis, image analysis) on interface content (e.g., content to be displayed or present via an interface such as a web page) and a content profiler 814 may create a content profile. A content profile may be created per interface (e.g., web page), for example, for each web page or interface content received from the content store 810. In some embodiments, a content profile may store the content itself, metadata associated with the content such as the Uniform Resource Locator (URL) of the content, characteristics of the content, usage history, historical effectiveness (e.g., if available) and/or other information or attributes associated with the content.

An engagement analyzer 816 may receive a content profile and a task profile, and may determine an engagement level of a user U on a task T. An engagement level of user U on a task T may be determined based on information such as the user's activities associated with a web page or interface via which the user is performing the task T, which information, for instance, may be specified in one or more of the content profile and the task profile.

The engagement analyzer 816 also may determine an engagement level of a user U on content C. An engagement level of user U on content C may be determined based on information such as the user's activities associated with a web page or interface, which includes content C.

A ranking and relevance score component 818 may receive a content profile and an engagement level of a user U on content C, and compute a relevant score associated with content C. For instance, a level of engagement (e.g., of user U on content C) may be computed, for example, as described above. A content item being analyzed and an engagement level may be fed with re-configurable input weights to a deep learning neural network algorithm with implicit and/or explicit learning feedback. Such deep learning neural network algorithm may have trained or learned the weights, for instance, based on historical data or training data set, to be able to predict a relevant score give input features comprising a content item and an engagement level with respect to the content item. A trained neural network may predict a relevant score, e.g., on a re-configurable scale of 1-5.

A progression and effectiveness estimator 820 may receive a user profile corresponding to a user U and an engagement level of a user U on content C, and may determine progression of a user U on a task T. The progression and effectiveness estimator 820 may also determine effectiveness of a user U on a task T.
